This non-magnetic material, also known as 2.0842 CuNi44, features a low temperature coefficient of electrical resistance and belongs to the group of resistance alloys, similar to manganin.Evek GmbH is your trusted source for constantan wire. Our online store offers a range of constantan wires that are ready for immediate delivery.2.0842 CuNi44 wire is easy to process, weld, and braze. It is highly resistant to corrosion and oxidation, and offers excellent ductility. Please note, it is not recommended for use in precision electrical resistors—for those applications, manganin is a better alternative.Common uses for constantan wire include: - Manufacturing thermocouples and heating resistors (suitable for operating temperatures up to 400-500°C) - Producing rheostats and potentiometers - Fabricating measuring resistorsKey properties of 2.0842 CuNi44 wire: - High electrical resistivity - Low temperature coefficient of resistance - High Seebeck coefficient - Excellent ductility - Good coefficient of expansion - Strong resistance to corrosion and oxidationFor purchasing constantan wire, please reach out to Evek GmbH. We offer high-quality constantan wires at competitive prices, always available from stock.
